MODE 0F OPERATING RAILROAD-STATION PUMPS.

i Specification of Letters Patent No.

T o all lwhom 'Lt may concern:

Be it known that I, IVILLIAH MCVEIGH, of Boone, in the county of Boone and State of Illinois, have invented certain new and useful Improvements in Station-Pumps, which I have described in the following specification and illustrated in the accompanying drawings with suficient clearness to enable others of competent skill to make and use my invention.

My invention consists in the arrangement and combination of parts, hereinafter described, by which the water is pumped into the reservoir, for supplying t-he engines, by the passing of the cars, as herein more fully set forth.

In the accompanying drawings Figure l, is a perspective view of the principal parts showing the operation of my invention. Fig. 2, is a transverse sectional elevation showing in part the arrangement of the cross levers. Fig. 3, is a longitudinal sectional elevation showing the construction and arrangement of the inclines upon which the cars operate. Fig. 4, is a plan representing the toggle-joint which carries the roller which operates upon the inclines.

A, A, is a railroad track made and laid in the ordinary manner, and B, is any kind of a car which may run upon it.

O, O, are two double inclined planes placed intermediate between the rails of the track. These inclined planes are attached to, and rest upon the ends of two levers D, D. These levers are hung in fulcrums E, which fulcrums E, E, are attached to cam levers F, F. The levers D, D, are

connected at the end opposite to that upon which the double inclines rest, to the lever J. This lever is hung upon a fulcrum in the center and is operated by the vibrations of the lever D, D. The end of one of these levers, or one end of the lever J, is con- 19,304, dated February 9, 1858.

nected to the pump rod Gr, and thus by means of the vibrations of the levers the pump H, is operated. The inclines are operated by the pressure of the roller I, attached to the bottom of the car by the toggle-joint K. This toggle-joint is adjusted by the screw L.

The roller should in no case be set lower than the bottom of the pilot on the engine; it may be raised altogether so as not to operate, should the train be found more than sufficient to furnish a supply of water. lhe ends of the inclined planes C, C, are kept from rising out of place .by catches (m, m,)

The operation is as follows: When a train passes over the road, every car upon which the roller and toggle-joint are placed in position for operating, operates upon the double inclines C, O, alternately, and by means of the levers, arranged as described, produces a reciprocating motion of the piston of the pump. The levers F, F, are made cam shaped at the end, so that by turning them over into the position opposite to that in which they are represented, the incline to which it is hung, or with which it is most immediately connected is let down by lowering the bearing of the lever to which the cam lever is attached. This lowers the incline so far as to leave it out of the reach of the roller I, and the pump is not operated.

Having thus fully described my invention, I claim- The combination of the roller I, the inclines C, C, the levers D, D', the lever J, and pump I-I, arranged as described for the purpose set forth.

WILLIAM MCVEIGH.
